Abstract
"MéTODO E DISPOSITIVO PARA AJUSTAR UM PARâMETRO (IDQ) DE UM DISPOSITIVO DE POTêNCIA MUDANDO UM SINAL DE ENTRADA (VG) PARA DITO DISPOSITIVO DE POTêNCIA". A presente invenção propõe um método para ajustar um parâmetro (IDQ) de um dispositivo de potência (1) mudando um sinal de entrada (VG) para dito dispositivo de potência, dito método incluindo as etapas de tomar (S2) uma amostra de um sinal de saída (POUT) de dito dispositivo de potência (1), detectar (S5) pelo menos um primeiro e um segundo nível de componente de sinal (PLST, P2ND) de dito sinal de saída amostrado (POUT), processar (S6) o pelo menos primeiro e segundo nível de componente de sinal detectado (P1ST, P2ND), decidir na base de um resultado obtido em dita etapa de processamento (S6), se uma compensação de uma mudança de dito parâmetro (IDQ) é requerida, e se uma tal mudança é para ser compensada, determinar (S8) um valor de mudança (<30>V) para dito sinal de entrada (VG) e ajustar (S9) o parâmetro (IDQ) mudando dito sinal de entrada (VG) por dito valor de mudança determinado (<30>V). Além disso, a presente invenção propõe um dispositivo correspondente."METHOD AND DEVICE FOR ADJUSTING A PARAMETER (IDQ) OF A POWER DEVICE BY CHANGING AN INPUT SIGNAL (VG) TO THIS POWER DEVICE". The present invention proposes a method to adjust a parameter (IDQ) of a power device (1) by changing an input signal (VG) to said power device, said method including the steps of taking (S2) a sample of a signal output (POUT) of said power device (1), detect (S5) at least a first and a second level of signal component (PLST, P2ND) of said sampled output signal (POUT), process (S6) the at least first and second level of detected signal component (P1ST, P2ND), decide on the basis of a result obtained in said processing step (S6), whether compensation for a change of said parameter (IDQ) is required, and if such a change is to be compensated, determine (S8) a change value (<30> V) for said input signal (VG) and adjust (S9) the parameter (IDQ) by changing said input signal (VG) by said determined change value (<30> V). In addition, the present invention proposes a corresponding device.
